Even with those who judge of conduct from the religious point of view, rather than from the ethical point of view, it is the same. Men who seek to propitiate God by inflicting pains on themselves, or refrain from pleasures to avoid offending him, do so to escape greater ultimate pains or to get greater ultimate pleasures. If by positive or negative suffering here, they expected to achieve more suffering hereafter, they would not do as they do. That which they now think duty they would not think duty if it promised eternal misery instead of eternal happiness. Nay, if there be any who believe that human beings were created to be unhappy, and that they ought to continue living to display their unhappiness for the satisfaction of their creator, such believers are obliged to use this standard of judgment; for the pleasure of their diabolical god is the end to be achieved. So that no school can avoid taking for the ultimate moral aim a desirable state of feeling called by whatever name--gratification, enjoyment, happiness. Pleasure somewhere, at some time, to some being or beings, is an inexpugnable element of the conception. It is as much a necessary form of moral intuition as space is a necessary form of intellectual intuition. CHAPTER IV. WAYS OF JUDGING CONDUCT. § 17. Intellectual progress is by no one trait so adequately characterized as by development of the idea of causation, since development of this idea involves development of so many other ideas. Before any way can be made, thought and language must have advanced far enough to render properties or attributes thinkable as such, apart from objects; which, in low stages of human intelligence, they are not. Again, even the simplest notion of cause, as we understand it, can be reached only after many like instances have been grouped into a simple generalization; and through all ascending steps, higher notions of causation imply wider notions of generality. Further, as there must be clustered in the mind concrete causes of many kinds before there can emerge the conception of cause, apart from particular causes, it follows that progress in abstractness of thought is implied. Concomitantly, there is implied the recognition of constant relations among phenomena, generating ideas of uniformity of sequence and of co-existence--the idea of natural law. These advances can go on only as fast as perceptions and resulting thoughts are made definite by the use of measures, serving to familiarize the mind with exact correspondence, truth, certainty. And only when growing science accumulates examples of quantitative relations, foreseen and verified, throughout a widening range of phenomena, does causation come to be conceived as necessary and universal. So that though all these cardinal conceptions aid one another in developing, we may properly say that the conception of causation especially depends for its development on the development of the rest; and therefore is the best measure of intellectual
